Abstract

La présente invention concerne un procédé de commande d'alimentation électrique de double appareil photo de terminal mobile, un système, et un terminal mobile. Le procédé comprend les étapes suivantes : lorsqu'il est détecté qu'une instruction de fonctionnement d'un utilisateur ou d'autres applications activent un appareil photo, déterminer si la condition actuelle est une condition d'utilisation spécifique ; si oui, commencer à alimenter électriquement un appareil photo correspondant à un numéro de série d'appareil photo et allumer l'appareil photo ; si ce n'est pas le cas, commencer à alimenter électriquement un appareil photo correspondant à un numéro de série d'appareil photo par défaut et allumer l'appareil photo.
